Tuberculosis (TB) is a major infectious disease associated increasingly with drug resistance. Thus, new anti-tubercular agents with novel mechanisms of action are urgently required for the treatment of drug-resistant TB. In prior work, we identified compound 1 (cyclohexyl(4-(isoquinolin-5-ylsulfonyl)piperazin-1-yl)methanone) and showed that its anti-tubercular activity is attributable to inhibition
结核病(TB)是一种越来越多的与耐药性相关的主要传染病。因此,迫切需要具有新颖作用机制的新抗结核药来治疗耐药性TB。在先前的工作中,我们鉴定了化合物1(环己基(4-(异喹啉-5-基磺酰基)哌嗪-1-基)甲酮),并显示其抗结核活性可归因于肌苷5'-单磷酸脱氢酶(IMPDH)的抑制作用。 )在结核分枝杆菌中。在本研究中,我们通过在生化和全细胞分析中合成和评估类似物对结核分枝杆菌IMPDH的抑制活性,探索了化合物1周围的构效关系。进行X射线晶体学分析以阐明所选类似物与IMPDH的结合方式。我们确定了环己基的重要性,
